The timing diagram of the function block for this application
shows the dependence of operating mode contacts OS01Q1
and OS01Q2 on the state of coils OS01I1 and OS01I2, the
enable coil OS01UL and the acceptance coil OS01SM.

"Operating mode switch" example: timing
diagram
a
Operating mode 1 is not accepted as no enable is present via
OS01UL for the operating mode change.
b
Enable for operating mode change present via OS01UL. Oper-
ating mode 1 is accepted with a rising edge at OS01SM.
c
Enable for operating mode change is removed. As operating
mode 1 was active at this point, this mode is retained until the
enable is present again at OS01UL. If the coil OS01UL picks up,
the function block detects that no operating mode is selected
and the closed contact OS01Q1 opens.
d
Acceptance of operating mode 2.
e
Operating mode 2 is taken again, since an enable for the oper-
ating mode is present via OS01UL
